Having played mostly Orcs, I can tell you that Orcland is so big that you can usually find a few places that are not over-run by bots. But, you might have to walk around a while. Also, I have never seen a bot in the Cave of Trials in Orcland. (A little tough for lvl 16, and no herbs, but, no bots.)
Also, when you get past lvl 25 or so, there are places you can hunt for several levels in the Schuttgart region where it's very un-populated. The thing is, there are no private stores either, so if you do hunt in Schuttgart, stock up on shots and wh before you go there. It's way too expensive to be TPing back to to Gludio or Dion (or Gludio) to re-plenish every hour or so.
Leave DE area and head over to Gludin. Windmill hill is a decent place to lvl your toon. You might wanna check out abboned camp (spelling???) as well. Neutral Zone near Gludio is a decent place too. High density mobs.
As for the shots pick them up from the MDT (no port costs). Usualy there are shops who sell shots.
Felmere's Harvest Groud. (sorry if spelled wrong)
I have yet to find ANY bots there on my server.
Th red bears should be just right for your lvl (located up the road to the north of the tp point from gludin)
You can easily lvl there many many levels by progressivly going to harder mobs.
For some reason, whenever I start a new toon, I end up exp'ing in elven noob land :)
Spiders when you follow the road to the west past the crossroad (they are like lvl 15-17, port "elven forest" from gk and walk west), after that neutral zone (lycanthropes) or right outside Dion (Monster Eye Seacher for really good xp, Enku Orc Champion, Hobgoblin, all 21-22). Dion has the advantage that the mobs are literally right outside the town gates, so it is easy to go back to town to restock, you don't even need a soe.

To my good surprise I didn't see any either, in Cave of trials, recently.
In C1 it was really really crowded.
